See the figure below. COO ;cf8591p of Origin: The selection of the ADC channel that you want to use is selectable via the control byte register and configurable via software as well as the Analog Output Management. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering.

The necessary instructions you can send the i2C bus a 1 st byte containing the address of the device and a second byte in the internal configuration of the device. Connect the two pins next to the potentiometer of the PCF module with the yellow jumper cap attached.

We can get the device address to the following binary value. The maximum conversion rate is given by the maximum speed of the I2C-bus. The upper nibble of the control register is used for pcf8591l the analog output, and for programming the analog inputs as single-ended or differential inputs. Subscribers can get exclusive discounts,freebies and giveaways! The address always has to be sent as the first byte after the start cpf8591p in the I2C-bus protocol.

Standard Pack Production Pack. The PCF can be used in closed loop control system, low power converter for remote data acquisition, battery operated equipment, and Acquisition of analog values in automotive, audio and TV applications. For more details please refer to the Datasheet Source Code. SunFounder Apr 13 at To identify the i2C address of the device used the pin A0, A1, or A2.

Get updates,discounts, and special offers to win free gift! The address consists of a fixed part and a programmable part.

Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of up to eight devices connected to the I2C-bus without additional hardware.

Leave this field empty. The lower nibble selects one of the analog input channels defined by the upper nibble see Fig. The values to be assigned to the control byte to select various analog input configuration in 4 single-ended inputs Bit4 and Bit5 to Zero will be: Address, control and data to and from the device are transferred serially via the two-line bidirectional I2C-bus.

RS Components Statement of conformity. The PCF is ready to scan and send the data to the i2C channel.
